3 1. PURPOSE This SOP aims to ensure that valproate is appropriately prescribed in female patients in line with current MHRA Guidance. Valproate should not routinely be prescribed to: female children, female adolescents, women of childbearing potential or pregnant women unless there is a positive risk benefit balance and the patient is aware of and accepts that risk. 2. BACKGROUND In January 2015 the MHRA published new guidance regarding the use of sodium valproate in women of child bearing age. Following a Europe-wide review, it was concluded that children exposed in utero to valproate are at a high risk of serious developmental disorders (in up to 30-40% of cases) and/or congenital malformations (in approximately 10% of cases). A Drug Safety Update was issued by the MHRA advising that valproate, should not be prescribed to female children, female adolescents, women of childbearing potential or pregnant women unless other treatments are ineffective or not tolerated. Despite this, a survey of women taking valproate in 2016 found that 20% were not aware of the risks of valproate in pregnancy and <20% had received any of the educational materials. Subsequently, a Patient Safety Alert (PSA) has been issued, requiring organisations to undertake a systematic identification of girls and women who are taking valproate and to ensure that the resources contained within the toolkit are used to support them to make an informed choice. MHRA guidance states that valproate treatment must be started and supervised by a specialist experienced in managing epilepsy or bipolar disorder. The potential benefits of prescribing valproate MUST be carefully balanced against the risks when prescribing valproate for the first time, at routine treatment reviews, when a female child reaches puberty and when a woman plans pregnancy or becomes pregnant. The Medicines and Healthcare products Regulatory Agency (MHRA) have developed Communication materials Valproate toolkit to support discussion of these risks with women of childbearing potential and girls who take valproate. The MHRA toolkit aims to help ensure that female patients are better informed about the risks of taking valproate during pregnancy. The materials should be used to support discussion of the risks. CWPT Healthcare Professionals may come into contact with patients who are taking valproate which has been initiated within CWPT (e.g. mental health, learning disability, children s services) or external to CWPT (e.g. neurologists). 3. PROCEDURE This SOP applies to the prescribing of all formulations of valproate, including: sodium valproate, valproate semisodium and valproic acid (thereafter referred to as valproate). It is applicable to all indications including prescribing in: epilepsy, manic episodes associated with bipolar disorder and migraine prophylaxis.

4 There may be patients who lack capacity to understand the valproate guidance due to a learning disability. For these patients, documentation should be made of the capacity assessment and discussion of Valproate risks with carer so that a Best Interest decision can be made regarding continuing or changing the treatment. ALL female patients MUST be informed of, and understand: The risks associated with valproate during pregnancy The need to use effective contraception The need for regular review of treatment The need to rapidly consult if a pregnancy is planned or is confirmed To achieve this Healthcare Professionals have the following responsibilities: 3.1 Treatment initiated by CWPT services: Prescribers: New Valproate patients (See algorithm 1): The Prescriber must use the toolkit to support discussion of the risks of valproate prescribing with female patients The Prescriber must supply the patient/carer with a copy of the Patient s Guide The Prescriber must discuss the risks with the patient and ensure that the patient fully understands the necessary information If the decision is made to start valproate therapy: The completed consultation checklist must be added to the patient s medical records as a permanent record of the discussion A flag ( valproate- discussion had ) must be added to carenotes to indicate that the patient is prescribed valproate and that a discussion has been had regarding risk of treatment Existing Valproate Patients (See algorithm 1): A prescriber may also identify female patients who are already prescribed valproate. When this happens the prescriber must clarify if a review has already taken place e.g. by checking on carenotes (i.e. valproate- discussion had is flagged). The above procedure (3.1.2) for new patients must be followed where this has not occurred. At each appointment the prescriber should re-iterate the message about the risks with valproate. The discussion should be documented, noting if the valproate is to be continued Patients transferred to GP care: Where a patient is started on valproate, or identified as being on valproate, information about the discussion of risks, where the person has been referred for contraception, etc. should be shared with the GP.

5 Pharmacists: Pharmacists should supply a copy of the Patient Card when valproate is dispensed. This information should be discussed with the patient to ensure that the message is understood and to clarify if there are any questions All Other Healthcare Professionals (See algorithm 3): If a Healthcare Professional identifies a female patient prescribed valproate they should check if the patient has had a discussion with their prescriber about taking valproate. (The Healthcare professional may also be able to check the entry on Carenotes to identify if there is a flag to indicate that the valproate prescribing has been reviewed and the patient has been supplied with the appropriate information). If this has not happened the professional should refer the patient to the CWPT prescriber for review (if still open to that service; if not, to the GP) and create an alert on carenotes ( valproate- no discussion) if their service uses carenotes. If the service does not use carenotes, a record of the referral should be made in the patient notes. 4.1 Treatment initiated external to CWPT (e.g. by neurologist) 4.1. Prescribers (See algorithm 2) A prescriber may identify female patients who are already prescribed valproate which has been initiated external to CWPT. Unless they are prescribing the valproate they are not responsible for reviewing the appropriateness of the treatment, but are responsible for checking that the patient is aware of the risk of treatment The prescriber must clarify if a discussion has already taken place with the patient about the risks of treatment e.g. by checking with the patient or on carenotes ( valproate- discussion had is flagged) If the discussion has not already taken place the prescriber should discuss the risks with the patient using the MHRA toolkit. The discussion should be documented and a flag ( valproate discussion had ) created on carenotes (if the service uses carenotes). The prescriber will not be in a position to evaluate the risk:benefit of treatment with valproate. If the patient is considering not taking valproate due to the risks, she should be referred back to the service that initiated the treatment/gp If the discussion has already taken place, the prescriber should reiterate the message about the risks with valproate at each appointment Pharmacists Pharmacists should supply a copy of the Patient Card when valproate is dispensed. This information should be discussed with the patient to ensure that the message is understood and to clarify if there are any questions All Other Healthcare Professionals (See algorithm 4) If a Healthcare Professional identifies a female patient prescribed valproate they should check if the patient has had a discussion about taking valproate with their

6 prescriber. (The Healthcare professional may also be able to check the entry on Carenotes to identify if there is a flag to indicate that the valproate prescribing has been reviewed and the patient has been supplied with the appropriate information). If this has not happened the professional should suggest that the patient contacts the initiating service (if still open to that service) or GP for review and create an alert on carenotes ( valproate- no discussion) if their service uses carenotes. If the service does not use carenotes, a record of the discussion should be made in the patient notes.
